Centrifugal Compressor Test Rig

Centrifugal Compressor Test Rig The test rig consists of a centrifugal blower driven by a variable speed electric motor. A motor controller is used to regulate the blower speed. Ducts are fitted to inlet & outlet of the blower. A damper in inlet duct is provided to regulate the intake air flow of the blower. A Pitot tube with differential manometer is used to measure the air flow rate. Two manometers are provided to measure intake & discharge pressure of air. Two temperature sensors are used to measure the air temperature at inlet & outlet. Blower speed & power consumption are displayed using digital panel indicators. Experimental Capabilities: • To investigate performance of Centrifugal Compressor. • To study effect of blower speed on delivery pressure, air flow rate. • To study blower characteristics as function of speed, air flow rate & delivery pressure. • To determine mechanical efficiency of centrifugal compressor.
